structure and the reactivity of metallic derivatives of tauto- 

 meric systems and later of the tautomeric systems themselves. 

 Nesmeyanov, and his associates, ascertained the mechanism of 

 electrophilic replacement in saturated carbon atoms. He ob- 

 tained diphenylchloronium, diphenylbromium, triphenyloxonium 

 salts and studied the mechanism of decomposition of these 

 -onium salts and of various diazonium and iodonium compounds. 

 Nesmayanov and associates made a thorough study of the re- 

 actions of the new metallo -organic, "sandwich" compounds, the 

 ferrocene, and ascertained their aromatic character. He also 

 carried out a series of syntheses based on olefin telomeriz- 

 ation. He and K. A. Kocheshkov edited a series of monographs 

 "Synthetic Methods in the Field of Metallo -Organic Com- 

 pounds." Based on his experiment, Nesmeyanov advanced a 

 series of theoretical ideas on the future development of the 

 theory of chemical structure. 



Nesmeyanov was Chairman of the Council for Coordinating 

 Scientific Work of the Academies of Sciences of Union Re- 

 publics. He was Chairman of the Editorial Publishing Council 

 of the U.S.S.R. Academy of Sciences. 



In 1962, Nesmeyanov was awarded the M. V. Lomonosov 

 Gold Medal.
